Side hustles are a relatively new idea, with the term only being coined in the 1950s. A side hustle is a way people earn income outside of their regular jobs. The phrase has gained huge popularity in the past decade as more people are looking at ways to make a bit of extra cash. It's no coincidence that this popularity has paralleled a growth in the gig economy- with the advent of companies like Uber and AirBnB, many people can now bring in a second income without making huge adjustments to their lifestyle.
